jamieson greer is right in pointing out that carney's reaction is unhinged and emotional, and not careful or thought through. 

is trump worse than mckinley or hoover? no. he's not worse than bush II. he's not worse than reagan. he's about the same as clinton.

going off on rants about the sky falling and the global order rupturing because you didn't get the deal you wanted right this minute (but will get it if you wait a few years) is not careful, steady leadership, it's governing via hysterical fits. it's the mirror image of trump himself.
